Ingredients
- 1 cup plus 2 tablespoons (143 grams) all-purpose flour
- 1/2 cup (43 grams) unsweetened cocoa (measured correctly)
- 1 cup (200 grams) light brown sugar
- 1 teaspoon fine sea salt
- 1 teaspoon baking soda
- 4 tablespoons (57 grams) unsalted butter, melted
- 1/4 cup fresh vegetable oil
- 1/2 cup (120 grams) full fat sour cream or plain whole milk yogurt, at room temperature
- 2 large eggs plus 1 egg yolk, at room temperature
- 2 teaspoons vanilla extract
- 1 cup (136 grams) shredded zucchini (from about 1 medium zucchini)
- 1 cup (170 grams) semisweet chocolate chips
- 1/2 cup (63 grams) powdered sugar, sifted
- 1 tablespoon milk
Instructions
- Step 1: Preheat the oven to 350°F. Line an 8 by 8-inch metal baking pan with parchment paper, then spray it with nonstick cooking spray.
- Step 2: In a large bowl, whisk together the flour, cocoa, brown sugar, salt, and baking soda until well combined.
- Step 3: In a small bowl, whisk together the melted butter, vegetable oil, sour cream (or yogurt), eggs, egg yolk, and vanilla extract.
- Step 4: Make a well in the center of the dry ingredients and pour in the wet ingredients. Stir gently until a few streaks of flour remain.
- Step 5: Squeeze out any excess moisture from the shredded zucchini before folding it into the batter. This helps prevent a gummy texture. Then fold in the chocolate chips until just combined.
- Step 6: Pour the batter into the prepared pan and bake for about 30 minutes, or until a toothpick inserted in the center comes out clean. It’s normal if the cake sinks slightly in the middle due to its moistness.
- Step 7: Let the cake cool completely in the pan on a wire rack before frosting.
- Step 8: To make the frosting, stir together the sifted powdered sugar and milk in a medium bowl with a fork until smooth, thick, but still pourable.
- Step 9: Drizzle the frosting evenly over the cooled cake and allow it to set before serving.
Tips & Variations
- For best texture, remove as much moisture as possible from the shredded zucchini by squeezing it in a clean kitchen towel or using paper towels.
- Swap semisweet chocolate chips for dark chocolate or white chocolate chips depending on your preference.
- Try adding a teaspoon of instant espresso powder to the dry ingredients to enhance the chocolate flavor.
- Use Greek yogurt instead of sour cream for a slightly tangier taste and added protein.
Storage
Store the cake in an airtight container at room temperature for up to 4 days. If you prefer, you can refrigerate it to extend freshness, but let it come to room temperature before serving for the best texture. Leftovers can be gently reheated in the microwave for 10-15 seconds if desired.

FAQs
Can I use zucchini that is not shredded?
It’s best to shred the zucchini finely to ensure it blends well into the batter and distributes moisture evenly. Larger pieces may alter the texture and make the cake less uniform.
Is the zucchini taste noticeable in the cake?
No, when shredded and mixed properly, zucchini adds moistness without a strong vegetable flavor, making it a great way to sneak in some extra nutrition.

- 1 cup (200 grams) light brown sugar
- 1 teaspoon fine sea salt

- 1 cup (170 grams) semisweet chocolate chips
Frosting:
- 1/2 cup (63 grams) powdered sugar, sifted
- 1 tablespoon milk
Instructions
- Preheat oven and prepare pan: Preheat your oven to 350°F (175°C). Line an 8 by 8-inch metal baking pan with parchment paper and spray with nonstick cooking spray to ensure easy cake removal.
- Combine dry ingredients: In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, light brown sugar, fine sea salt, and baking soda until thoroughly mixed.
- Mix wet ingredients: In a separate small bowl, whisk melted unsalted butter, vegetable oil, full-fat sour cream (or plain whole milk yogurt), eggs, egg yolk, and vanilla extract until fully combined.
- Incorporate wet into dry: Create a well in the center of the dry ingredients and pour in the wet mixture. Stir gently until a few flour streaks remain; do not overmix. Ensure the shredded zucchini has excess moisture squeezed out, then fold it and the semisweet chocolate chips into the batter just until combined.
- Bake the cake: Pour the batter evenly into the prepared pan. Bake in the preheated oven for 30 minutes or until a toothpick inserted in the center comes out clean. Expect a slightly sunken center due to the cake’s moist richness.
- Cool the cake: Remove the cake from the oven and let it cool completely in the pan before glazing.
- Prepare frosting: In a medium bowl, stir together sifted powdered sugar and milk using a fork until the glaze is smooth, thick, but still pourable.
- Glaze the cake: Drizzle the prepared glaze evenly over the cooled cake surface. Allow the frosting to set before slicing and serving.
- Storage: Store the cake in an airtight container at room temperature for up to 4 days to maintain freshness and moistness.
Notes
- To avoid a gummy cake texture, be sure to squeeze out as much moisture as possible from the shredded zucchini before adding it to the batter.
- Using full-fat sour cream or plain whole milk yogurt adds moisture and richness to the cake.
- If you prefer, the frosting can be adjusted by adding more milk for a thinner glaze or more powdered sugar for a thicker consistency.
- Ensure eggs and sour cream/yogurt are at room temperature to help the batter blend smoothly and rise evenly.
- Line the baking pan with parchment paper beyond the edges for easy removal of the cake.
